Compatible Replacement Earpads

These earpads fit Sony WH-CH500, ZX330B, ZX330BT, WH-CH310, WH-CH110 and WH-CH250 headphones. They are intended for owners who need to refresh worn or cracked original cushions. The 70 mm diameter matches the listed models. Buyers with other headphone series should verify dimensions before ordering.

Tool-Free Installation

The pads slide onto the earcups without tools or adhesives. Removal of the old cushions is equally straightforward. A common issue is a loose fit if the headphone mounting points differ slightly from the listed models; the supplied note allows a 1-2 cm measurement tolerance. No hardware or wiring changes are required.

Sponge Cushion Performance

The soft sponge material provides passive noise isolation and aims to restore audio fidelity. The 70 mm size covers the driver area for the compatible models. Dense foam may compress over time, reducing seal and isolation. The package includes one pair of earpads only; no headband padding or additional parts are supplied.
